Item # 146506, Quick Release Valves

The Airflex quick release valve (QRV) is a pneumatic in-line, three-way valve designed to automatically close upon pressurization and open to exhaust when a pressure drop occurs in the supply line. The valve provides an exhaust port close to the pressurized chamber of the device being controlled rather than exhausting through long supply lines and/or control components. The end result is a reduction in lag time between the signal to exhaust and response.
